Answer— 2
Explanation- simple math
Answer: Option c.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
Given the equation:
Solve for "y" in order to write in Slope-Intercept form:
Now you can identify that that the slope and the y-intercept are:
A posive slope means that the the line moves upward from left to right.
With this information, you can conclude that the the graph that best represents the given equation is the graph shown in the Option c.
Answer: The function could be y= - 3 cos x
Solution:
One x-intercept is (pi/2,0): We can use a trigonometric function like cosine that has x-intercept (pi/2,0).
The domain of the cosine function is the set of all real numbers.
The maximum value is 3, then the amplitude must be 3: y = 3 cos x
The y-intercept is (0,-3) then it is the functio y = 3 cos x, reflected around the x-axis: y = - 3 cos x
Answer:
x=-12
Step-by-step explanation:
Start by getting all of the x values on one side and other to the other.
1/3x-3/4x=1+4
Now simplify. Because 1/3 and 3/4 do not have the same denominator, find the least common factor between 3 and 4 (which is 12) and make the fractions have denominators of 12.
4/12x-9/12x=5
-5/12x=5
x=5*(12/-5)=60/-5=-12
x=-12
Answer:
6 millimeters.
Step-by-step explanation:
1 millimeter : 4 metres
x millimeters : 24 metres
x = (24÷4) × 1
x = 6 × 1
x = 6 millimeters
